There is 1000 MB in every GB so that would be 0.756302 GB No that is wrong there are 1024Mb in 1 GB (stupid manufacturers of HDD's rate them at 1000mb, so you never actually get what they say their HDD capacity is. e.g. My HDD is rated at 640 Gb but it is only really 598Gb. When you buy Ram you get what you pay for e.g. 512mb is 512mb of ram) I hope that clears that up for you. Its false advertising at it's most obvious.

Depends on what kind of recorder you are looking for. I'd advise you to take a look on dvdrecordersreviews.com
It is perfectly fine to play an Xbox 360 without an HDD. In fact, Microsoft produces a cover for the area where you plug the HDD in just incase you choose not to use an HDD.
